I am attempting to re-learn AIJ for a course I am teaching this semester, but I am having trouble when I go to place apertures.  I keep getting the following error: " WCS mode requested but no valid WCS coordinates stored. ABORTING.

Can someone give me some advice on how too resolve this issue. I'm sure it is me!
